' ROLLER-SKATE.

Specification of Letters ratent. Application filed May 21,

Patented Dec. 7, 1909. 1909. Serial No. 497,414.

To all whom it may concern:

Be it known that I,IJOHN N UTTALL', a citizen of the United States, residing in Chicopee, Hampden county, in the State of Mas sachusetts, have invented certain new and useful Improvements in Roller-Skates, of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof. i

This invention relates to the construction of frames for roller skates and is particularly' concerned with the formation of the plates, both toe and heel, including the adusting and clamping devices, and with the means for securing the trucks to the frames.

One object of the invention is to secure great rigidity without increase in weight,

and another is to simplify and improve the construction, particularly so as to reduce the number of parts and the number of rivets requlred to hold the parts together.

Other objects and useful purposes ac-' complished by the improved construction will appear more clearly in this specification in which the improvements are described with reference to the embodiment thereof shown in the accompanying drawings, in which i Figure 1 is a top view of the improved skate. Fig. 2 is a longitudinal section on the irregular Iplane indicated by the broken line 22 of ig. 1 with parts inelevation.

Fig. 3- is a view partly in front end elevation and partly in transverse section on an irregular plane, the toe plate and forward extension of the heel plate being in section approximately on the plane indicated by the line 33 of Fig. 2, while the toe clamp bracket is shown in elevation as to its right hand end and approximately in central longitudinal section as to the central lug and left hand portion. Fig. tion on the plane indicated by the line4-4 of Fig. 2, looking in the dlrection of the arrows, the forward truck and its immediate appurtenances being omitted, while the wheels and shaft are indicated by dotted lines. Fig.- 5 is a view in section on the plane indicated by the line 55 of Fig. 2, looking in the direction of the arrows. Fig. 6 1s a rear end elevation,"partly in section on the plane indicated by the line 6-6 of Fig. 2.

The foot plate, as usual, comprises a rear portion or heel plate a and a forward portion or toe plate b. Each of these plates may be stiffened by depending flanges, as at a and b respectively. By the present improvements, however, each of these plates is greatly stifiened and strengthened by longitudinal corrugations. The heel plate has in its rearward portion a corrugations a which are sunken orv pressed downward from above, while in its forward extension a it has corrugations a in line with the corrugations a but raised orpressed upwardly from below. This heel plate, asusual, is provided with any suitable means whereby it may be secured to the foot, such as the slotted cars a to receive the usual straps, and is also slotted longitudinally, as at a, to receive the lockin bolt 0.

The toe plate 6 has a downward end, as at If, and is slotted in the bend, as 6 to permit the forward extension a of the heel plate to pass forward under the front portion 6* of the toeplate. The rearward extension b of the toe plate passes under the heel plate and is also corrugated longitudinally, as at 6", Such corrugations being in line respectively with the corrugations a and a of the lleel plate, and being sunken or pressed down fromabove so as to fit upon the rearward corrugations a of the heel plate and be guided and steadied thereby. The rearward extension 6 of the toe plate is also slotted longitudinally, as at b, in line with the longitudinal slot a in the heel plate, toreceive the locking screw 0, the slotting of .both plates permitting a greater length of longitudinal adjustment of the skate frame.

The clamping screw 0, as before indicated, passes through the two slots a and 3), its head-c being slightly flattened on opposite sides, as shown at c in Fig. 1, so as to stand between the forward corrugations a of the heel plate and be held thereby from turning. The clamp 0 which is slipped on the lower end of the bolt 0 and is pressed upward by the nut 0 spans the ribs or corform to the corrugations, so that it also is.

held from turning and has -a---wider bearing 'against the underside of the-toe plate, thereby" securing a' firmer and more rigid clamping of thetwo plates.

The rear bracket d and the forward bracket 6 are each'shouldered, at each side, as at d and 6. respectively, to form guides, respectively, for the rearward extension of the toe plate and for the forward extension of the heel. plate.

' The toe clamp bracket f isso constructed, in one piece, as to form a guide for the adjusting screw, a continuous guide for the clamps, and a guide for the forward part of the heel plate, being secured'to the toe plate by two rivets f only. To accomplish this result, it is formed in one piece as shown clearly in Figs. 2-, 3 and 8, having head pieces f which are riveted to the underside of the toe plate, dependingclamp guides f, a depressed flat portion f which connects the head pieces and forms a guide for the forward extension of the heel plate, as shown in Fig. 3, and also to form lateral guides for the toe-clamps g and also carry a central lug f which is turned down and is notched on its underside, as at f, to engage the clamping screw h in the circumferential groove h formed therefor. The toe-clamps g, which are threaded for engagement with the-adjusting screw h in the usual manner, are supported by the outer clamp guides f and are also guided in the continuous guide formed by the depressed bridge pieces f, while the forward end of the heel plate which rests upon the bridge pieces is guided and steadied by the head pieces f passing through the guide way formed therefor between the bridge pieces and the toe plate above.

Each bracket, forward and rear, is formed as usual, the forward bracket e, for example, having downwardly and forwardly extending arms e", between which is received the axle bracket e which carries the axle c with its wheel e". Between the axle bracket c and the bracket e is interposed a cushion or bumper e and the bumper cup 6, which has end flanges e to retain the bumper e in place and is itselfusually secured in place by being riveted to the bracket 6. In the present case, however, the rivets are dispensed with and thefianges e are extended I to form ears 6 to. overlap the arms c of the bracket e and so hold the bumper cup. and the bumper from displacement.

- I It will be understood of course that the various features, of improvement might be used independently of one another and are notnecessar ly combined in one structure,

except so far ashereinbefore indicated, and

- corrugations, a toe plate having its rearward that details of construction might be changed without departing from the spirit of the invention.

l. I claim as my invention:

1. In a roller skate the combination of a heel plate having its rearportion corrugated longitudinally with downwardly pressed corrugations and its forward extension corrugated longitudinally with upwardly pressed extension corrugated longitudinally with downwardly pressed corrugations to fit upon the downwardly pressed corrugations of the heel plate, andmeans to clamp said plates together adjustably.
